It sure looks good under the hood, but the price is too high for me

[brettco]

That engine is as cool as it gets!

[FUNFER2]

I agree !
How much was the distributor ?
That's the way to go but, it's even more $$$

[fkemmerer]

Kevin,

I don't remeber the exact cost of the distributor but its not that different from an electronnic MSD billet distributor. BTW, attached are the dyno output numbers for the engine. There is a complete parts list and specs for it in my gallery if you're interested.

Summit is/was selling Accel dual sync distributor for FE for less than $300 couple of years ago. Part # Accel 77200 for small cap housing.

Fred- truly a dream engine. You cobra looks very nice also. Looking at your photo's, is it not completed yet ? Nice color too.

Thanks, Fred, I'm taking notes for the future. I love the system. Outstanding. How much maintenance is involved after installation and tuning?

[fkemmerer]

I would expect very little mtce. after the initial tune in the car is completed. I have a Blown and Inject Vette running the same type of setup and the only mtce I have done to it in the last 3 years is to change oil and spark plugs. These systems adapt to conditions, wear on the engine, etc. pretty well and there is nothing that will wear out in the life of a "hobby car" like this.

The TWM cost is not $10k, look on my site. www.thormotorsports1.com The install is relatively easy if you are somewhat adept at wrench handling. The entire setup install time should be under 16 hours. Most Kirkhams come with a plugged return bung in the fuel tank which simplifies things a little. I can turn you on to someone in your area that can do fine tuning on a chassis dyno. The performance and ease of tuning over webers is well worth it in the long run.

Al, as soon as the money tree in the backyard sprouts some new growth, I'll be knocking on your door. Thank you.

Its a 100A unit from Powermaster. I'd consider a 100A alternator about the minimum for a car with an EFI setup. It works on a Cobra because these is not much else in terms of electronnics or lighting that will use alot of power. Big items are the EFI Computer, Ignition Box, Fuel Pump, Electric Fans, and then the lighting system on the car.

I use a stock replacement 65A unit on my Cobra. Cheap at Autozone and carries a lifetime warrenty. Never have a problem with it not keeping up. I do drive with the lights on pretty often, makes it easier to be seen. But I don't have any kind of sound equipment.

[COBRAMAN 484]

I tried a 100amp powermaster but it wouldn't fit, it was about .125 inches to long. I picked up a 100 amp chrome motorola. It works fine the only problem I have is even with the smallist pully I could find, at night with the lights on when the engine is at idle (1000rpm) my wideband meter won't show the air fuel readings. It defaults to 14.7 when the voltage is below 12volts. I use a tempo regulator and have it set at 14.5 volts but i don't think I want to set it any higher.

Sounds like a good solution. You can install the 100A powermaster by using a 2 groove pulley set and a spacer on the alternator mount. This is what I did with my motor. To improve the appearance, I had a local machinist remove the back unused groove on the water pump pulley. If you look closely at the damper pulley in the picture below, you can see the second groove.

I am preparing to install my engine in my cobra an I needed to remove the IAC assembly to re-orient it and to polish the chamber cover. I thought I'd post a few pictures for the IAC air block and plumbing under my TWM intake. As you can see, there is a distribution block just below where the rear intake breather would go on the TWM intake for my FE. A line runs from this block to each intake runner on the the TWM manifold.



Here's a picture of the inside of the intake ports - you can see the fittings where the IAC plumbing connects to the ports.



The following shows the IAC and cover reinstalled on the TWM intake. A 90 degree fitting and a custom made aluminum cover allow the IAC motor to mount neatly on the the back of the TWM intake.



With this setup, my FAST XFI computer can regulate the idle speed of the motor my allowing a controlled amount of air into the cyclinders at idle.

Nice job!!!!
